The Minecraft Guns Mods Weapons app will add different weapons, armor, and more to your Minecraft server. With it, you will be able to fight against other players on the server.
It is a very powerful application, so make sure you have the most powerful server on your machine. If you are on a weak machine, it might not be able to handle all the data, and you will not be able to play the game as it was before.
You will find a variety of different weapons. It is a very good idea to wear armor, as it will protect you from some of the attacks.
